' CARZBURETOR LOCK.

Application filed June 5, 1926; Serial No. 114,039.

g 9 This invention relates to a lockfor a carburetor, the general object of the invention being to provide/means for; preventing the throttle valve from beingopened beyond a certain extent so as to prevent-speeding. of a vehicle- Another objectof the invention is to so form thelock that it can be held in position bythe bolts which fasten the carburetor to the inlet manifold, the device being provided with [means for preventing removal of some i of such bolts when the device is in locked position.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated inthe accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, ref erence will be had to the accompanying;

drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figural is a perspective view of a carburetor and portion of the inlet manifold, :showing the lock in posit-ion. Figure 2 is an end View looking into the carburetor and showing the device in locked position. i

Figure 3 is, a perspective View of the de vice with the parts in open position.

As shown in these views, the device comprises a base or body 1 which is provided with the depending perforated ears 2 and the post'3 adjacent one end and the keeper member 4 at the other end, said member be ing provided with the keeper openings 5. An arm 6 is hingedly connected/to the post by the links 7 and said arm is provided with a channel-shaped head 8which will receive the member 4 when the arm is swung downwardly into closed position. The upper end of the head is provided with a slot 9 through which the end of the member 4 will pass when the parts are in closed positionand a lock 10 is carried by the outer end of the arm, with its outer edge in alignment with the inner wall of the slot so that the boltll of the look, when projected, 1 will extend across the slot and will thus engage one of the openings 5 tohold the parts in closed or lock is shown at 12. The armis provided removal by an unauthorized person.

' partly closed position. The keyhole of the with a depending projection 13 which may be ai ustably connected with the arm, if desire a i i The device is placed at the junction of the carburetor A. and the intake manifold B, the ears 2 overlapping the outer face of the enlarged lower portion otthe manifold, with the perforations aligning with the holes in the large portions of the manifold and carburetor sothat the bolts a which connect the carburetor and. manifold together will pass through the ears and, thus fastenthe device in place.

The arm A of the throttle valve of the carburetor will extend over thepart- 1 of the device so that when the arm 6 is in its lowest pos tion, the projection 13 will be struck by the said arm A when it has beenmoved it will not interfere with the movement oi" said armand thus the motorcan be actuated the same as it the device were not in use.

When the device isin fully closed position, the lower portion of the head 8 will cover one of the bolts a and thus prevent the detachment of the carburetor from the nianifold in an attempt to remove the device. 7

From the foregoing, it will beseen that I have provided a lock for limiting theopening movement of the throttle valve of amovice being put in placegwithout changing any of the parts of the vehicle or'its motor and when in locked position, preventing its With this device, an owner of a vehicle can prevent the driver of the vehicle from driving the same at an excessive speed. By making the projection 13 adjustable, the device can be set to permit the maximum speed of the vehicle to be adjusted to any desired degree.

It is to be furtherunderstood that the right is reserved to change the construction so that it may be attachedto' carbi'lretors other than those which are attached at the junction of the two flanges, either with clamps or bolts.

any desired degree, even to the extent of holding the throttle valve entirely closed so that it can be used to prevent theft.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparentv I desire it to be understood that I may make changes in the construction and in the eon'ibiuation and arrangement of the several parts, provided that such changes fall within the scope ofthe appended claims.

Vhat I claim is 1. A device for preventing a motor vehicle being driven beyond a certain speed, comprising a body adapted to be held in place by the bolts which connect the carburetor with the inlet manifold, an arm hingedly connected with the body, a keeper member on the body, lock means on the arm for engaging the keeper member anda projection on the arm whichis engaged by thethrottle arm of the carburetor when the device is in closed position.

2. An attachment for a vehicle comprissing a base having perforated depending ears thereon adapted. to receive the bolts which connect the carburetor with the intake manifold and which has a central portion placed under the arm of the throttle valve, an arm hingedly connected with the base, a keeper member on the base, a casing on the arm for receiving the keeper member when the arm is in lowered position, said casing also covering one of the bolts when the arm is in low- SAMUEL CHARLES YOUNG.
